Storybook MDX: Dynamic Meta Title

How can I set a dynamic title property on a Storybook Meta component in a Markdown Extended *.stories.mdx file?

import { Meta } from '@storybook/addon-docs/blocks';

// displays title as 'undefined' in sidebar nav
<Meta title={conditionalValue ? 'foo' : 'bar'} />

I also tried wrapping Meta in a higher-order component, which triggers an error: Unexpected default export without title

import { Meta } from '@storybook/addon-docs/blocks';

export const MetaCustom = (props) => {
  const title = conditionalValue ? props.foo : props.bar;
  return <Meta title={title} />;
};

// mdx stories file
<MetaCustom foo="foo" bar="bar" />
storybook reactjs

I tried creating a util function and import into the mdx and seems like it is working.

utils.js

export function generateTitle (condition) {
   return condition ? 'foo' : 'bar'
}

Component.stories.mdx

import { generateTitle } from './utils.js';

    <Meta
      title={generateTitle(true)}
    />

Hope that helps!
